This feasibility study will (1) assess adolescents' willingness to be randomized; (2) pilot the intervention, attention control strategies (e.g., adolescents' 'own best efforts' at managing arthritis), and outcome measures; (3) determine adolescents' perceptions regarding acceptability of the web-based intervention; and (4) obtain estimates of treatment effects in primary (HRQL) and secondary (knowledge, coping, self-efficacy, stress, treatment adherence, pain) outcome measures to inform the calculation of appropriate sample size for the future RCT.
